(Continued)
*1: This command is valid while Fast Mode.
*2: This command is valid while RESET = VID.
*3: The valid addresses are A6 to A0.
*4: This command is valid while Hi-ROM mode.
Notes: 1. Address bits A11 to A20 = X = “H” or “L” for all address commands except or Program Address (PA), Sector
Address (SA), and Bank Address (BA).
2. Bus operations are defined in Tables 3 and 4.
3. RA = Address of the memory location to be read
PA = Address of the memory location to be programmed
Addresses are latched on the falling edge of the write pulse.
SA = Address of the sector to be erased. The combination of A20, A19, A18, A17, A16, A15, A14, A13, and
A12 will uniquely select any sector.
BA = Bank Address (A15 to A20)
4. RD = Data read from location RA during read operation.
PD = Data to be programmed at location PA. Data is latched on the falling edge of write pulse.
5. SPA = Sector group address to be protected. Set sector group address (SGA) and (A6, A1, A0) = (0, 1, 0).
SD = Sector group protection verify data. Output 01h at protected sector group addresses and output
00h at unprotected sector group addresses.
6. HRA = Address of the Hi-ROM area
29DL32XTE (Top Boot Type) Word Mode: 1F8000h to 1FFFFFh
Byte Mode: 3F0000h to 3FFFFFh
29DL32XBE (Bottom Boot Type) Word Mode: 000000h to 007FFFh
Byte Mode: 000000h to 00FFFFh
7. HRBA = Bank Address of the Hi-ROM area
29DL32XTE (Top Boot Type) :A15 = A16= A17 = A18 = A19 = A20 = 1
29DL32XBE (Bottom Boot Type) :A15 = A16= A17 = A18 = A19 = A20 = 0
8. The system should generate the following address patterns:
Word Mode: 555h or 2AAh to addresses A0 to A10
Byte Mode: AAAh or 555h to addresses A–1 and A0 to A10
9. Both Read/Reset commands are functionally equivalent, resetting the device to the read mode.
